CULTNATOR.

Specification of Letters Patent.

Patented March 2 7, 1906.

Application filed August 17,1905. Serial No. 274,545.

To all whom it' may concer-ni.:

Be it known that I, FREDERICK E. SCHAAL,

a citizen of theUnited States, residing at Sewby declare the following to be a full, clear, and

exact description of the invention,- such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cultivator attachments.

The object of the invention is to provide an attachment for Wheel-cultivators which may be lswung to and maintained at various angles, the means for holding the attachmentin its adjusted position being operable from the handle of the implement.

Another object of the invention resides in the provision of an exceedingly sim le, inexpensive, durable,'and efficient attac ment of the nature stated embodying such characteristics that it may be readily attached to or detached from any of the wheeled cultivators now in use.

With these and other objects in view the present invention consists in the. combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it

- being understood that changes in the form,

pro ortion, size, and minor details maybe ma e within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a portion of a cultivator embodying my invention. Fig. 2 is a top plan-view.' Fig. 3 is a sectional view through the beamsv and casting on the line a a of Fig. 2. Fig. 4

is a detail view of the casting detached from the cultivator. Fig. 5 is a detailed view of the U-shap'ed toothed late.

Referring now to t e drawings, therel is shown a portion of a wheeledcultivator, the reference character 1' designating a crank-axe provided atone end with a sleeve 2, adjacent which and .mounted upon the extremity of the axle 1 is a ground-wheel 3. `Mounted upon this sleeve 2 is a beam-coupling member comprising the parts 4 and 5, coupled together by means'of a suitable pivot-pin 6.

The part 5 of the coupling has upper and lower ears 7 and 8', between which are tted the forward ends of the beams 8 and 9 in any suitable manner. By reason of this pivotal connection of the parts 4 and 5 of the couplingthe beams 8 and 9 are permitted to move laterally of the cultivator at both sides thereof, it being understood that there is another pair of beams at the opposite side of the crank-axle 1 of the cultivator.

By reason of the two sets of beams, which vare designed to work upon opposite sides of rows of corn or other vegetables, there is in the use of the cultivator, by reason of inequalities of ground, more or less side draft,

necessitating constant attention on the part of the operator, who is compelled to frequently right the beams with reference to the rows of vegetables by pulling accordingly upon the handles 10 of the cultivator. Such attention to the cultivator and movements of the handles is a constant strain upon vthe operator, and my invention is therefore intended principally to offset the strain and unneces-l sary labor. In other words, inorder to obviate the necessity of continually righting the Vposition of the beams and their points 11 and 12, respectively, lwhich 'are secured lto the standards 13 of each beam, and to also obvi-v ate the strain upon the operator` I secure to.

the under faces of vthe beams 8 and 9a U- shaped plate 14, whose legs are secured, bymeans of suitable bolts 15, to the ears 17 and 18 of the coupling member 4, with its bight portion 16 provided with a series of teeth 19, which latter are disposed ina direction of the cultivator-points 11 and 12.

It will beseen that the inner ends of the cultivator-beams 8 and 9 converge to a meeting-point, and inthe space between the beams 8 and 9 immediately in the rear of their meeting engagement I secure the upper longitudinal grooved portion .21 ofthe castin 2O of my improvement. gitudinal grooves 21 ofthe casting 20 two Walls 22 and 23 result, which walls are provided with alining perforations 24 for the receptionof a suitable bolt 25, Whichpasses therethrou h and also through the correspending casting 20 between the latter. This casting 20 is placed in such position with respect to By reason of `the on- IOO earns 8 and, 9 for 4securing the the beams and the lJ-shaped plate 14 as to ermit the beveledl tonguel25 at one end there-of to fit beneath the U-shaped late 14 i and assist in supporting the same eneath the`beams l8 and 9. The end of the casting 20 opposite the lip 25 is extended beyond the Walls 22' and 23 and beneath thebottom of th( grooves 21, as indicated by the reference character 26, and terminates in a short upright projection 27, provided with a perforation 28. This perforation 28 of the short upright 21 is arranged in direct alinement with the longitudinal bore 29 of the casting 20, the bottom of said bore being in alinement with the upper face of the inner end of the lip 25 with its top beneath the bottom of the longitudinal groove or bifurcation 21.

Fitted for sliding movement in the bore 29 and through the perforation 28 of the short upright 27 is a rod 30, which latter extends rearwardly to the lower end of the handles,`

where it is pivoted to one end of the angleplate 31, which latter is pivoted to the handle, with its opposite end connected to a rod 32, which latter has its opposite end engaged in the eye 33 of the handle-lever 34, which latter is pivotally secured in any suitable manner near the upper end of the corresponding handle.

The rod is held normally in engagement at its free end with the teeth 19 of the U- shaped plate 14 by means of a lhelical spring encircling the same between the short upright 27 and the corresponding end of the .walls 22 and 23 ofthe casting 20. However,

when it is desired tol disengage the rod 30 from the teeth 19 of the U-shaped plate 14 ressure upon the hand-.lever 34 toward the liandle of the cultivator will pull the rod 30 out of engagement with the teeth against the action of the spring 35 and permit a shifting of the beams with respect toa pivotal movement ofthe part wit the part 4 of the coupling aforesaid. It will `.be apparent, therefore, that when the cultivator is ,to operate u on opposite sides of the row and evenly t erewith the rod 30 is engaged with the pro er tooth 19 of the U-shaped member 14, an thereby hold the beams and the coupling in one positionwith respect to the axle of the cultivator.

From the foregoing it will be seen that my improved attachment is very simple, and consequently inexpensive of manufacture, and I desire to call attention to the fact-that by reason of the taper of the casting 20 the same ma be wedged tightly between the beams 8 an 9, with the shoulders 36- and 37 of thev casting held tightly against the lower faces of the respective beams, as clearly shown in the drawings.

What is claimed isp 4 A device of the character described comprising a casting having a lip projecting from one end and an extension at ,the opposite end provided with a perforated upright, the said casting having a longitudinal bore throughout its length above the level of the upper faces of the said lip and extension, a rod mounted for sliding movement through said bore, and a spring encircling the rod between the casting and said upright.

In testimony whereof l aflix my signature in presence of two Witnesses.
